A servo track writer for use in a hard disc drive is provided, which includes a plate-shaped base member, a hard disc drive fixed on the upper surface of the base member, and a clock head unit spaced by a predetermined distance apart from the hard disc drive, for recording and reading out a clock signal on and from the hard disc drive, respectively. The servo track writer includes a sliding transfer unit for transferring the clock head unit toward or far from the hard disc drive, and an adjusting screw which extends from one side of a supporting member supporting the clock head unit toward the hard disc drive and adaptively contacts the side surface of the hard disc drive functioning as a stopper when the clock head unit moves toward the hard disc drive. The servo track writer can maintain the constant distance between a clock head unit and the hard disc drive since the adjusting screw installed in the supporting member supporting the clock head unit adaptively contacts one side of the hard disc drive functioning as a stopper, although the hard disc drive moves by a certain distance apart from the clock head unit due to an external force, to thereby detect a clock signal recorded on the hard disc drive with ease.
